Implementation Assistance Program – The Arizona Department of Transportation is applying Pavement Renewal Solutions to renew pavement assets quickly and cost-effectively and to minimize the impacts on road users, to lower the costs of owning these assets, to decrease the use of new pavement, and to reduce the environmental footprint.

Implementation Assistance Program – The California Department of Transportation is implementing the use of rePave software to more accurately scope the pavement strategy most appropriate for the situation and existing conditions for a variety of projects. Training and webinars are critical to implementation.

Implementation Assistance Program – The Kentucky Transportation Cabinet is conducting training to identify and prove the effectiveness of at least one technique or process that could be implemented in a programmatic manner throughout the State. The goal is the development of an ongoing program that utilizes the identified technique or process.

Implementation Assistance Program – The Louisiana Department of Transportation is exploring whether Pavement Renewal systems could speed up the decision making process with respect to what treatment will be placed on a roadway and timing for rehabilitation.

Implementation Assistance Program – The Minnesota Department of Transportation is conducting training and discussion of the R23 tool, applying the tool in case studies, evaluating the tool’s procedures and processes relative to those used by the department, and documenting the results.

Implementation Assistance Program – The New Jersey Department of Transportation will provide educational training to develop a guidance which will assist in the decision making process to determine which existing pavement can be used as part of renewal projects.

Implementation Assistance Program – The New York Department of Transportation is identifying suitable sites and examining relevant data to develop a decision tool to identify and select candidates for rehab/reconstruction that also have cost saving benefits from re-use of existing materials (maximize the use of the previous service life).

Implementation Assistance Program – The North Dakota Department of Transportation is conducting training in the Pavement Renewal Solutions software so it may effectively be implemented in the scoping process.

Implementation Assistance Program – The Utah Department of Transportation is conducting workshops to explore how training and the use of this program by other States could be of value when scoping future projects.

Challenge

Highway agencies need guidance to help better understand when and where it can be
beneficial to use existing pavements to speed rehabilitation project delivery. Use
of existing pavement can reduce cost; however, it is not always a viable solution.
By being able to identify projects where this technique can be successful, highway
agencies can apply the process with more confidence, and reap the benefits of lower
cost, and more rapidly rehabilitated facilities.

Solution

An interactive web-based pavement design scoping tool provides much-needed guidance
for deciding where and under what conditions to use existing pavement as part of
roadway renewal projects. It includes approaches for employing existing pavements
in-place to ensure longer service life for roads using asphalt, concrete, and innovative
materials. The product also identifies new alternatives to renewal approaches; and
examines the advantages and disadvantages of each approach, the circumstances under
which each should be considered, different construction techniques, and methods
for integrating recycled materials with adjacent materials and road structures.

This guide will help transportation agencies make better decisions with regard to
pavement renewal projects by using existing pavement as part of the design. Transportation
agencies, drivers, highway workers, contractors, and taxpayers will benefit from
time savings based on rapid reuse of existing materials, reduced costs for new pavement,
and an accelerated construction process. Washington DOT has utilized the recommendations
offered in this guide, and has realized a 30 percent cost savings and a 50 percent
reduction in user delay costs over the life of the new pavement. This approach delivers
long-lasting value by promoting durable and dependable roads, while reducing the
environmental footprint because less new pavement is required.

Benefits

Decreased use of new pavements.

Shorter construction time, resulting in reduced exposure of travelers and construction
workers to work zone hazards.

A better return on investment based on longer pavement service life.

Reduced environmental footprint, based on decreased use of new materials.

Save Lives

Shorter construction periods reduce risks and enhance safety for the traveling public and construction workers.
